The vort weakens more than the 12z run which probably explains why its both colder and worse with the coastal. Result is a smidge colder and an asshair drier (for around DC at least)
When do you think we could have a good handle on the vort pass and backend snow situation? It seems that the models that are the best with the WAA for my area sorta miss with the backend and vise versa. Want to make an updated forecast for my friends and family but am waiting for more agreement on that last part, and thanks for the post!
Since you’re giving out snowfall ranges for various places do you think the Ashburn/Reston area should be in a solid 6-10 range? Seems like at this point the WAA should get us well and if we’re lucky with the coastal we could her higher end amounts
either way it still gets us to 7ish inches by the end of its run with at least 2-6 more with the coastal fluff so not even a bad run verbatim, but is a little worrying if it nudges any further north
As someone who is that age I don’t remember anything much before 2016 besides glimpses of storms. I vaguely remember the 2016 blizzard but wish I could recall more about it. The Monday system may be the first time I can truly remember getting 10+ inches of snow (ig Jan 2019 counts too but yk what I mean)
That was incredible! Thunder snow, watching the clouds come in, the progression from melted flakes to a snow globe, this may be one of my favorite winter events ever.
Is there any great way to tell a sounding between borderline sleet and snow? I know roughly that 600 feet plus of warm nose is where trouble happens but hard to tell if thats on the sounding maps.
The funny part is that the storm is almost split in two around the DC area with roughly half of the snowfall from the WAA and half from the coastal. Not sure I would really want to bet on the coastal giving that much but who knows.
